Two things to check.
One, check your parental settings. It's possible that your account has been limited by a parent to not allow custom content.
Also, if the game is already in progress, you won't be able to download the map.
The custom maps server is no more as of yesterday afternoon. Keep your head up to see if Hired Gun puts it up again (probably with a different name).
